Question

When given a problem with a temperature in Celsius, what do you need to do before plugging in your variables?

Answer 1

Before using a temperature value in Celsius in various equations, it's necessary to convert it into the appropriate unit, such as Fahrenheit or Kelvin, using the correct conversion equations, and then check if the result is reasonable.

Step-by-step explanation:

When given a problem with a temperature in Celsius, before plugging in your variables, you need to ensure that you are using the correct units for the equations at hand. For example, if you need to convert from Celsius to Fahrenheit, you would use the formula T°F = (9/5 × T°C) + 32. When working with gas law problems, it's important to use Kelvin, so you would convert degrees Celsius to Kelvin with the equation T(K) = T°C + 273.15.

In general, you should:

1. Select the correct conversion equation.
2. Substitute the known variables along with their units into the equation.
3. Obtain numerical solutions with appropriate units.
4. Check if your answer is reasonable and makes sense.
